*1
*1 NX701 or NJ501 CPU Unit, and NY-series Controller: The variable name is _PLC_TraceSta[0..3].
NX1P2, NJ301 or NJ101 CPU Unit: The variable name is _PLC_TraceSta[0..1].
*2 _sTRACE_STA[]
*3 Refer to the NJ/NX-series CPU Unit Software User's Manual (Cat. No. W501) or NY-series Industrial Panel PC / Industrial
Box PC Software User's Manual (Cat. No. W558) for details.
Additional Information
• Refer to the NJ/NX-series CPU Unit Software User's Manual (Cat. No. W501) or NY-series Industrial
Panel PC / Industrial Box PC Software User's Manual (Cat. No. W558) for details on data tracing.
• Tracing is used to sample the values of specified variables under specified conditions. The conditions
are specified from the Sysmac Studio.
• This instruction can be located in more than one place in the user program. Programming can be
written to sample according to specific conditions.
• Point can be suitably set so that you can see which sampled values on the Data Trace Window in the
Sysmac Studio were returned by which TraceSamp instruction. Point will default to 0 if it is omitted.
Precautions for Correct Use
• Return value Out is not used when the instruction is used in ST.
• In the following cases, nothing is done and the instruction ends normally.
• Data tracing is stopped.
• The sampling timing is not set to sampling instructions in the trace settings.
• The value of TraceNo is not the trace number set from the Sysmac Studio.
• An error occurs in the following case. ENO will be FALSE.
• The value of TraceNo is outside of the valid range.
